It also provides one example of use (in i40e). Features: - log types are identified by a string - at registration, a uniq identifier is associated to a log type - each log type can have its level changed dynamically - extend command line parameters to set the log level of a specific type, or logs matching a regular expression - keep compat with other legacy types (eal, malloc, ring, user*, etc... keep their hardcoded log type value) At the end, when, we can expect that all non-dataplane logs are moved to be dynamic, so we can enable/disable them at runtime, without recompiling. Many debug options can probably be removed from configuration: $ git grep DEBUG config/common_base | wc -l 89 Comments are welcome!
